About the improvements
The Didcot and surrounding areas major infrastructure scheme will provide vital transport infrastructure to reduce congestion and enable more reliable journey times, improve pedestrian and cycling connectivity, and support new employment sites and housing in and around Didcot.
The project includes four highway sections that incorporate improvements to existing roads, the construction of new roads, new walking and cycle routes, and will help to facilitate new and enhanced bus services.
Key benefits:
- 19km of walking and cycling paths to improve pedestrian and cycle connectivity for work and leisure trips
- 18 new bus stops to provide more sustainable travel options in and around Didcot
- Reduce congestion and improve air quality in surrounding villages and parishes
- Enable more jobs in the local area in new and existing employment sites
- Support expected housing growth in the local area
